Specification of Letters Patent.

Patented Jan. 26, 1915.

Application filed February 13, 1914. Serial No. 818,499.

To all whom it may concern:

Be it known that I, Mosns M. EMERSON, a citizen of the United States,and a resident of Ellensburg, in the county ofKittitas and State oflVashington, have in vented a new and useful Improvement inFire-Hydrants, of which the following is a specification.

My present invention relates to fire hydrants, and the object thereof isto provide a simple and efficient mechanism, wherein a free opening forthe passage of water through the hydrant, unobstructed by internalmechanism, is constituted.

Further objects of my invention have to do with the detailedconstruction in certain respects to be hereinafter more fully de scribedwith reference to the accompanying drawing, forming part of thespecification, and in. which,

Figure 1 is a side elevation, Fig. 2 is a central vertical sectionthrough the lower portion including the valve. Fig. 3 is a. detailvertical cross section through the valve, taken on the line 33 of Fig. 1and illustrating the same in closed position. Fig. e is a similar view,illustrating the valve in open position, and Fig. 5 is a cross sectionthrough the upper portion of the standpipe, taken substantially on theline 5---5 of Fig. 1.

Referring now to these figures, the stand pipe A of my improved hydrantmay be of any required diameter and may be cast one piece. It ispreferably made or built up of sections a, a and a however, as I haveshown in the several figures, the lower sections a and a being providedat their abutting ends with flanges a and a, respectively, which flangesabut one another and are secured together in order to join the sectionsa and a at a point substantially level with the ground line. The uppersec tions a and a may be threadedly united or otherwise joined at theirabutting ends and the latter section is preferably provided with a pairof laterally projecting outlets of in each of which is normally threadeda closing plug B, as best shown in Fig. 5. The top of the upper sectiona is also provided with a flange a, a top C being secured upon thisflange in order to close the upper section and form an air chamber inthe head of the standpipe above the outlets a in order to relieve thewater hammer. The lower end of the lower section a of the standpipe isconnected, by means of an elbow D, vith the horizontal feed pipe E, andbetween the elbow D and the adjacent end of the feed pipe E is a shortvalve section F in which a vertically reciprocatory gate valve F isdisposed.

Projecting upwardly from the valve section F is a dome or casting G inwhich the upper portion of the valve F may work, this upper portion ofthe valve being threadedly engaged by the lower end it of an operatinggate rod H extending upwardly along one side of the standpipe andthrough a surrounding tube or sleeve I to protect the same below thesurface of the ground, the extreme upper end of the rod H being extendedthrough portions of the connecting flanges a and (4* above mentioned andprovided with a circular flange or collar 2, seated between theseflanges a and a in order to constitute a thrust bearing.

As seen in Figs. 1 and 2 the upper eX- tremity of rod which terminatesslightly above the Flanges a and a" is squared to receive the similarlyshaped socket k of a rotatable rod H extending upwardly along the uppersections a" and a above the surface of the ground and having its upperend journaled through the flange a and cap'C at one side and alsoprovided with a squared upper extremity h Thus the upper ends of therods H and H, being similarly squared, are each adapted to receive awrench or like implement by which the lower rod H may be rotated toraise or lower the valve F as desired, so that in case of accident,should the upper portion of the hydrant be broken off, the valve .F"might still be operated by an implement in connection witl the thenexposed end rod H as will be seen by reference to Fig. 2.

Referring now to Figs. 2, 3 and a. it will be seen that the valve F isprovided with a vertical channel f, the lower end of which communicateswith a branch port f extending through one face of the valve in thedirection of the elbow D and adjacent the lower edge of the valve, theupper end of the channel 7 communicating with a lateral branch 7extending through one side of the valve and adapted, when the valve isin closed position, to register and communicate with the upper lateralportion of a channel f formed vertically in one side wall of the valvepipe section F and open at its ion lower end. It will also be noted thatthe relatively opposite side edge of the valve F has inclined portions7, which cooperate with similar inclined inner faces of the valve pipesection F, so that the valve F will, along its side edges, be snuglyseated in both the closed and opened positions thereof, respectively,shown in Figs. 8 and 4:. V

In operation with the valve F raised and open, water rushes underpressure through the feed pipe E and upwardly through the standpipe tothe outlets a but when the valve is lowered to closed position and therush of water thereby checked, a quantity of the water will be left inthe standpipe A and might, unless discharged, freeze therein in coldweather and cause bursting of the standpipe. lVith the channeled valve Iemploy, however, it will be seen that the water so held in the standpipewill find its way out through the channels 7", f, f and f and inasmuchas the branch channel f is located adjacent the lower edge of the valve,practically all of the water in the standpipe may be removed throughsiphon action when the head of the water falls below that point whereingravity alone would cause its discharge.

The several parts otherwise than those particularly described, may beformed in any suitable manner although 1 preferably cast the elbow Dwith an angular blocking shoe (Z in order to prevent disconnection fromthe feed pipe resulting from main pressure.

My inventlon provides a hydrant whlch,

from the foregoing, may be readily seen to be economical and highlyefficient and in which no restrictions are imposed upon the free passageof liquid therethrough when the valve is open and the hydrant in use,there being no internal mechanism to cocupy any portion of the area ofthe valve section or the standpipe in this position of the parts.

I claim 1. In a hydrant, the combination of a standpipe having a freeunobstructed passage for the flow of liquid therethrough in use, a valvepipe section disposed adjacent the lower end of the standpipe andprovided with a vertical channel in one side wall having a lateral portat its upper end opening into the interior of the pipe section, and agate valve movable vertically in the said valve pipe section and havinga vertical channel communicating at its lower end with a port openingthrough the face of the valve adjacent the standpipe and leading at itsupper end to a lateral branch channel opening through one side edge ofthe valve and adapted to communicate with the lateral port of the wallchannel when the valve is in closed position.

2. In a hydrant, the combination of a standpipe, a main, a valve pipesection disposed between the standpipe and the main, and a gate valvedisposed transversely within and across the valve pipe section andmovable vertically with respect thereto,

said valve and said valve pipe section hav- 1 ing channels thereinadapted to register and communicate when the valve is in closed positionand to form a continuous fluid passage, the inner end of which openstoward the standpipe at the lower end of the valve and the outer end ofwhich opens exteriorly through one side wall of the valve pipe sectionlaterally from the valve, all for the purpose described.

3. In a hydrant, the combination of a standpipe having a freeunobstructed passage therethrough for the liquid in use and formed insections certain of which have connecting flanges secured togethersubstantially at the ground line, a valve for controlling the supply ofliquid to the standpipe, a main valve operating rod rotatable to controlmovement of the valve and having a squared upper extremity projectingslightly above the said connecting flanges, a cap closing the upper endof the standpipe, and a supplemental valve operating rod having asquared socket at its lower end to fit the squared end of the main rod,said supplemental rod extending upwardly along the exposed portion ofthe standpipe and having its upper end journaled through the cap at oneside and provided with a squared extremity, all for the purposedescribed.
